Well, knowing my party we would certainly not.

We had some "they are too strong" encounters in the past ... NPCs were yelling at us that they will stall them and we should run ... exactly the LotR "run you fools" scene ... but we (to our DM discomfort) said "then we die fighting" ...
He learned tho, in next scenario he used infinite spawn and added 5 enemies each round, so we finaly understand he REALLY dont want us to fight here.

But it was fun. ^_^
But even if ... so what?
I mean it was their decision to ignore all the hints and red flags, it was their decision to start a fight or pick those lines that started it, it it all consequences of their own actions.
And sure, some snowflakes that were expecting railroading and plot armor from DM would certainly melt ... but sometimes that is for the best.
